3 days ago · Terrestrial plants rely on protection conferred by their outer coverings to defend against desiccation, bruising, and microbial invasion. For food staples such as potato tubers, the periderm contains the phellem (tuber skin) which creates a hydrophobic barrier by depositing macromolecular composites comprised of waxes, soluble phenolics, and a complex aliphatic suberin polyester (or suberin ...
2 days ago · By introducing genes that confer resistance to diseases, parasites, and other pests, we can improve crop yield and prevent loss by biologic events. This means GM crops actually require fewer chemical inputs than non-GM counterparts. Over the last 20 years, GMOs have reduced pesticide applications by 8.2% and helped increase crop yields by 22%.
1 day ago · A GMO is a genetically modified organism, meaning it has had genes modified for a certain reason (typically, to improve growth rates, nutritional content, pest resistance, or make a product more sustainable or easier/more cost-effective to produce). Until the 1980s, this was done through selective breeding (something that's still done today, of ...
2 days ago · The pivotal role of SA in SAR has been highlighted through the studies on genetically modified Arabidopsis and tobacco plants expressing bacterial SA hydroxylases. These plants, which were unable to accumulate large levels of SA, showed a lack of ability to establish systemic resistance to necrotizing infections.
3 days ago · on May 15, 2024. At times, potato growers may experience poor emergence of potato plants. There are number of reasons why potato plants may not emerge properly. A detailed guide compiled by renowned North American potato specialists is intended to provide a comprehensive list of common problems that can cause poor potato emergence and stand.
3 days ago · Variations in sweet potato genotypes include skin and flesh colour, depth of rooting, shape and size of root storage, partitioning of dry matter content, and variation in resistance to biotic and abiotic stress (McGregor & LaBonte, 2006; Sakaigaichi et al., 2024; Vimala & Hariprakash, 2011).
3 days ago · The research was part of the U-potato Plan led by Huang. Potatoes are a staple food for more than 1.3 billion people worldwide, experts said, but breeding techniques lag far behind those of other popular crops such as rice, maize and wheat due to genetic complexity. The conventional potato is tetraploid, meaning it has four sets of chromosomes.
